IMPROVEMENT INSTIRRUPS.

Specification forming part of Letters Patent No. 157,786, dated December15, 1874; application filed October 12, 1874.

To all whom fit may concern Be it known that I, JOHN BULL, ofChattanooga, in the county of Hamilton, and in the State of Tennessee,have invented certain new and useful Improvements in Stirrups; and dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecication.

The nature of my invention consists in the construction and arrangementof a springstirrup, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side view of a stirrup embodyingvmy improvement. Fig. 2 isa side view of the spring attachment, and Fig. 3 is a horizontal sectionof the same.

A represents an ordinary stirrup, made of a single piece of wood bent inproper shape, and having a metallic cross-bar, B, fastened across itsupper end. Through the center of the cross-bar B passes a shank or stem,O, the upper end of which is formed or provided with a loop, D, for theattachment of the stir-Y rup-strap. The shank O, below the cross-bar B,passes through two circular metallic disks, G G1, and the shank has, onits lower end, a head or button, a, to prevent its being withdrawn fromthe disks. In the disk G are fast cned a series of rods, b, which passdownward through holes in the disk G1, and their lower ends are fastenedin a disk, G2. Around each rod b, between the disks G Gl, is placed aspiral spring, d. The rods b, with their springs d., are arranged in acircle around the center shank O, whereby the springs are made to bearor act equally on all sides.

I am aware that the attachment of springs to a stirrup is not new, and Ido, therefore, not claim such, broadly, as being my invention.

By my arrangement of the springs in a circular form around the shankbetween the disks or plates, the pressure of the foot is equalized, nomatter whether the foot is in serted directly in the middle of thestirrup or to either side.

Having thus. fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with a stirrup, A, having cross-bar B, of theswivel-shank O, with loop D and head a, the circular disks G G1 G2, andthe rods b, with springs d, arranged in circular form around the shankO, all substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this24th day of September, 1874.
